I am occasionally unable to download https://releases.wikimedia.org/mediawiki/1.26/mediawiki-1.26.2.tar.gz (current MediaWiki release linked from https://www.mediawiki.org/wiki/Download). Sometimes it works fine, sometimes it returns a zero-byte response. This was first reported on #mediawiki by KDDLB.
